DESCRIPTION

Colostomy Bag Cleaning System Background of the Invention

A colostomy is a surgical intervention in which the colon or part of it is removed and the digestive tract joins an opening made in the abdominal wall, thus allowing digestive waste to pass through the abdomen. Typically, the waste is collected in a waterproof bag that is fixed to the opening. The opening resulting from a colectomy is known as "ostomy" or "stoma", and the waterproof bag that collects digestive waste is known as a colostomy bag.

Typically, a person who has suffered a colostomy should remove and empty the colostomy bag several times each day and must irrigate the ostomy at least every other day to maintain good health and hygiene conditions. An ostomy is irrigated by applying running water to the ostomy and allowing water to drain.

Examples of prior art ostomy irrigation devices or cleaning systems comprising a closed drainage system that eliminates the need to have to be placed on a patent are disclosed in the US patent application publication US 2003/0229324. toilet, since they have their own collection system, although this system is difficult to use and practically requires the person to lie down for satisfactory use, as shown in Figure 1. US Patent 6,408,861 shows a cleaning bag for urine bags that consists of a very complicated system associated with a shower in a bathtub and that also has a difficult operation and a very elaborate design. Patent 5,454,389 shows an ostomy bag cleaning device that incorporates a mechanism to introduce water into a colostomy bag and subsequently evacuate the waste material to a storage chamber. This device is complicated to use and does not allow simple cleaning of the colostomy bag without removing it from the person.

Patents 5,096,503 and 4,194,506 both describe as a general concept introduction rods that are introduced upwards by the lower part of the colostomy bag inside the same, being difficult in both systems to have to introduce a rod to through the bottom of the colostomy bag, with the possible presence of drips and leaks of materials, so that this technique is not satisfactory to clean the colostomy bag when the person continues to carry the bag. Patent 5,738,668 is similar and, again, describes the introduction upwards of a probe into the bag for cleaning, again appearing the same inherent problems. Patent 6,532,971 describes a hygienic bag cleaning device that is designed to simultaneously clean the inside and outside of the colostomy bag and which consists of a complicated mechanism, functioning again with the colostomy bag removed from the person. US 6,224,581 discloses a colostomy bag cleaning apparatus having a mounting plate, the cleaning method being carried out again with the bag removed from the person and creating significant complications to be able to carry out the cleaning of simple and effective way.

US Patent 4,654,037 describes an ostomy bag that has a built-in irrigator to clean the bag. The bag comprises separate front and rear walls and sealed around its peripheries to define a collection chamber and has a bottom opening that can be closed in order to drain the contents collected from the bag to be discarded. An opening is arranged in one of the walls to receive a patient's stoma. A fluid distribution tube is located inside the bag and is provided with multiple openings, so that a protruding end of the tube can be connected to a source of cleaning fluid to allow purging the contents of the bag without removing the bag from the bag. patient body

US Patent Publication 2005/0283126 describes a colostomy bag cleaning system. The description refers to a closed drainage system to irrigate colostomy bags in which the bag is irrigated and cleaned while in its functional position, associated with the person. More specifically, a collector is mounted inside the colostomy bag with an access for pressurized water from the outside, preferably the collector carrying out a dispersion of fluid or water on the top of the bag and causing gravity its subsequent dripping down, through the bag, and outwards, through the lower opening, preferably the residue of the bag being dragged through the water and passing to a toilet, where the user purges the bag until all the waste is completely cleaned of it and pour them into the toilet. A water source from the toilet itself or another suitable water source supplies the pressurized water to the collector inside the top of the colostomy bag. This system allows to obtain a large volume of irrigation of the colostomy bag and removes dirt during cleaning of the bag when removed from the person, the possibility of spills, odors and the spread of infectious diseases.

US Patent Publication 2005/0075616 describes ostomy tools and systems and processes for use. Waste management for people with an ostomy (ostomized) and, therefore, must carry an ostomy bag, is carried out through ostomy processes, systems and tools comprising versatile latent tubes. Such tools include ostomy bags, filters, connectors and transport vessels. The tools are especially useful, for example, for the control of the location and disposition of ostomy residues (and their odors) when the ostomized person performs demanding or unusual routine tasks associated with the care and maintenance of the ostomy. The tools also help increase the confidence of the

Description of the invention

Figures 1 to 4 refer to a known pouch and colostomy system.

Referring in this case to Figure 1 of the drawings, the number 10 indicates a colostomy bag that has an opening 12 that is surrounded by a plastic ring 14 and that is fluid tightly attached to the bag 10 by means suitable, such as by adhesives or by any suitable known methods. The ring 14 is shaped with an edge that is designed for coupling to a similarly shaped ring and edge 14A mounted on a patch 16 joining the colostomy bag located in a person. The patch 16 is joined by a pressure sensitive adhesive located on the back of the patch itself, and the ring edges 14 and 14A, when snapping together, form a fluid tight seal between the ostomy 18 and the interior of the colostomy bag 10.

A cleaning system is formed by a circular manifold, generally indicated by the number 20, which is preferably made of a soft plastic and surrounds the interior of the opening 12 of the colostomy bag 10. A plurality of small holes 22 around the perimeter of the manifold 20 are arranged to allow the passage of a spray in multiple and random directions of pressurized water introduced through an access tube 24 that is connected to a water source, not shown , through a connection 26. Alternatively, the manifold 20 may be integrally formed around the opening 12, such as by thermal sealing or the like.

The colostomy bag 10 is designed to be opened at the lower end, generally identified by the number 30. In use, this Lower opening is wound and held in a position to close the opening, such as by a sealing procedure. which uses hook and loop material, indicating the same as loop material 32 and hook material 34. It can be seen that when this lower end 30 bends and the hook and loop joint is in position, the bag is sealed at the bottom. To selectively clean the bag and the exposed part of the ostomy, the bag is opened and placed on the toilet so that the water or irrigation cleaning solution that passes through the manifold 20 and the holes 22 goes down through the bag and exit through the lower opening 30 towards the toilet or the like, as shown in more detail in Figure 2 of the drawings.

Referring to Figure 2, it shows a normal toilet, generally indicated by the number 40, on which a person will sit, usually towards the back of the toilet seat, to use the invention. A flexible water or supply hose 42 is selectively connected to the connection 26 to supply pressurized water through the conduit 24 and to the manifold 20 for spraying through the holes 22. The water supply is carried out to through a connection, indicated generally by number 44, which is coupled to the normal water supply tube of the toilet, indicated by number 46, and which has the ability to control the flow of fluid by means of a valve, indicated by number 48, associated with conduit 42.

Therefore, referring to Figure 2, it can be seen that the person sits in the toilet seat, connects the conduit 42 to the connection 26 and then, by adjusting the valve 48 in an adjustable manner, supplies a sufficient amount of pressurized water to the collector to obtain a flow that cleanses the ostomy 18 and to obtain a cleaning action inside the colostomy bag 10, the waste being dragged to the Bottom and the toilet, as shown in general by number 50.

Referring in this case to Figure 3, it shows an embodiment in which the collector, generally identified with the number 20a, is associated with the ring 14A of the patch 16 which is attached to the person's skin over the opening Ostomy 18. In this embodiment, the manifold 20a includes an access connection 24A selectively connected to the water line 42, so that the regulated pressure water forms the spray through the holes 22a, generally indicated by the number 60 .

Referring in this case to Figure 4, it shows an embodiment in which the collector, indicated by

In general, by number 20b, it is located on the opening 12 of the colostomy bag 10. In this embodiment it is possible to use a similar water inlet or connection 24b. In this embodiment, the manifold 20b may be located adjacent to the top of the bag 10 to disperse water or pressurized cleaning fluid throughout the bag 10 to obtain a quick and efficient cleaning of the bag 10. Spraying the plurality of holes formed in the collector 20b will also pass over the exposed parts of the ostomy and around them for cleaning. It is possible to use the upper manifold 20b alone or with a manifold located around the ostomy opening if desired.

A top manifold according to the present invention is shown in Figure 5. More specifically, the manifold of Figure 5 is integrally formed in the bag 10 by thermally sealing the bag 10 along the line shown generally by number 80, which can extend from the edge of the bag, such as it is shown on the left side by number 82, and below the top of the bag to the right side, as indicated by number 84. The seal line 80 can mimic the shape of the top edge of the bag to form a collector with uniform dimensions throughout the upper part of the bag 10. The plurality of openings 86 are arranged through the heat sealed part 80, and they allow a flow with a random and multiple direction of water spray to be obtained from the manifold after being supplied under pressure to the manifold from the supply opening in the direction of arrow 88. The bag access opening is indicated fo In general, by means of the number 90, it is integrally formed in the bag 10 and can include a one-way valve 92 that prevents the return flow through the opening 90 in case of tightening or applying a force on the bag that causes the return of the fluid rising through the opening 90 of the bag. It is also possible to arrange a separator, generally indicated by the number 94, which is part of the thermally formed part of the collector and acts to direct the flow of water entering through the opening 90 in opposite directions in the collector around on the right and left sides of the bosa, as shown by the water circulation arrows, indicated generally by the number 96.

Therefore, it will be understood that, in the embodiment of Figure 5, water circulates in the direction indicated by arrow 88 through the one-way valve 92 and to the manifold formed by the thermally sealed line 80, and is directed substantially equal to the right and to the left through the separator 94, then circulating through the multiple openings 86 formed in the collector, as indicated by the number 96, which indicates the water flow. The plurality of openings 86 makes it possible to obtain a dispersion of water or cleaning solution from the collector throughout the bag 10, forming sheets and sprays of water in random directions from the upper part of the colostomy bag to the stoma opening, which circulate then into the lower opening and exit through it, as described above. Also open the openings 86a and 86b immediately adjacent to the outer edge of the bag, which send water sprayed to the inner edges of the bag for better cleaning of those surfaces.

Therefore, as shown in Figure 5, and also in the sectional configurations of Figures 8 and 9, the manifold is better and larger, being easy to manufacture integrally with the bag 10 via line 80 thermally sealed adjacent to the top of the bag. The randomly oriented openings 86 allow a quick and efficient cleaning of the entire bag 10 to be obtained. It will be understood that the bag 10 can be formed from two substantially flat flexible pieces with a similar form of polymer material and that are thermally sealed by the periphery in a thermally sealed line 80a, as can be seen in Figures 5 and 8.

Figure 9 shows the sectional part of the bag of Figure 5 taken on line 9-9, and it is shown in the way in which water is pressurized inside the manifold to form a tubular configuration in the collector itself when pressurized by water entering the direction of arrow 88, as shown in Figure 5.

Figure 8 shows the multiple openings 86 formed by the thermal seal through the thermal seal line 80 that forms the collector, as shown in Figure 5.

Figures 6 and 7 show fasteners 100 and 102 of hooks and loops that allow folding the bag 10 from the position shown in Figure 6, as indicated by arrow 104, to the position with half the size shown in the Figure 7. This is convenient on certain occasions, when the bag is not really full, to allow a person to carry a bag smaller than the bag with the total length of Figure 6, and greatly facilitates preventing the bag from disturbing when sleeping, thanks to its smaller size.

Therefore, it will be understood that the bag and the cleaning system according to the invention are very simple and economical to manufacture, and that embodiments using an integrated collector or collectors further improve these properties. In the embodiment of Figure 5, the thermal seal line 80 can be formed in the bag according to standard thermal seal procedures, simultaneously forming the openings 86 so as to produce a random and abundant flow, similar to a shower, from the openings, and the pressurized water being applied, through the supply opening 90, in the upper part of the manifold formed by the thermal seal line 80.

Therefore, it will be completely understandable that Figures 5, 8 and 9 show a thermally sealed bag configuration consisting of two chambers separated by a thermally sealed septum, line 80, which contains several communication holes 86 connecting the two chambers. . The upper chamber (or

5

10

fifteen

twenty

25

30

35

40

compartment) is the smallest of the two, the connection system to an external water supply being integrated therein. The lower chamber is the largest of the two, comprising the opening system of the bottom of the bag to allow its contents to be removed during cleaning. The communication holes 86 connecting the two chambers are strategically located to distribute the water that enters through the smaller or upper chamber so that it thoroughly cleans the entire interior of the larger (or lower) chamber. It will also thoroughly clean the area around the stoma opening, including the exposed surfaces of the stoma.

It is possible to carry out the thermal seal of the tube with respect to the film material and the outer perimeter and the geometry of the septum using RF sealing methods (radio frequency or dielectric). It is possible to use a pulse sealing in the outer perimeter and septum seals. In an RF seal method, the actual seal is carried out by placing the layers of the film material in an element called a receiver. The seal matrix, which is machined to the exact dimensions of the seal design, descends on the upper face of the film layers at a required pressure, and the RF is activated, which generates instantaneous heat at the interface of the materials of upper and lower film. This creates, for example, the desired seal and openings 86.

The holes 86 are created by machining grooves through the thermal seal matrix in the defined positions. Because the thermal sealing process requires two flat surfaces pressed together to create the seal, said grooves create interruptions in the flat surface and, therefore, do not press the materials towards each other in said positions. Because the material does not have intimate contact in these positions, it will not be sealed, thus creating the holes through the septum.

In the embodiment of Figure 5, the manifold has 18 steps having a width of approximately 0.229 cm (0.090 inches) when the material is arranged in a flat position. When the water distribution chamber (or compartment) is filled with pressurized water, the passage can change its geometry to a more round hole with an approximate diameter of 0.152 cm (0.06 inches). Its actual shape is probably more elongated, but the effective opening is that of a round hole with that cross section. The size of the openings 86 may vary as desired, for example, between a diameter of 0.127 and 0.305 cm (0.05 and 0.12 inches). The total number of openings 86 could also vary from about 14 to 24.

It should also be noted that the system is pressurized by pressurized water from a water line that normally supplies water to the toilet itself, or similarly. As also shown in Figure 5, it is possible to have an external orifice 110 associated with the bag 10 from the compartment for venting accumulated gas through a carbon filter 112, which therefore allows the evacuation of the odorless gas.

It will be understood that, although Figure 2 shows the pressurized water from a water line 46 that normally supplies water to the toilet itself, the invention contemplates any suitable source of water or pressure cleaning solution for feeding the collector or collectors according to the invention. For example, a water bottle capable of being squeezed can supply a suitable pressure fluid. Similarly, a small battery-activated pump with a water source can supply the desired fluid under pressure. It is believed that the invention will be ideal for a person to use in the bathroom of their own home. However, there may be cases in which you travel or do not have an installation that allows you to connect the water hose to the adapter 26 and the supply line 24 for the collector, so that any source of pressure cleaning solution can result adequate.

It will also be understood that the spray holes 22 of the collector of Figure 1 have no special function, except to provide a suitable and quite fine spray that will tend to wash, clean and irrigate the debris inside the colostomy bag itself to facilitate Cleaning in the shortest possible time. It has been proven that this system allows cleaning in a few minutes or less time, and can be carried out several times every day in a very convenient way thanks to the very simple application of pressurized water through the collector to clean one's own colostomy bag

It will be understood that the provision of a manifold disposed at the top of the colostomy bag and that provides a large spray pattern cleans the bag from top to bottom, and it has been found that it is desirable to arrange the manifold no lower than the opening 12 of the colostomy bag for attachment to stoma edge 14A. This allows to obtain a good circulation by gravity of the water used in the cleaning system, allowing it to circulate downwards through the bag, dragging all the waste and extracting it through the lower opening 30.

Referring in this case to Figures 10 and 11, alternative embodiments of the invention are shown with modifications made to the integral manifold structure according to the invention. More specifically, in the embodiments of Figs. 10 and 11, the collector 20 is integrally formed in the upper part of the colostomy bag or bag 10, the upper wall of the bag forming the upper part of the collector 20. The lower part of the collector 20 is provided with a series of point welds 86, which can be referred to as bounce point welds due to their function during the cleaning operation. The spot welds 86 together define the lower part of the manifold 20, causing the limitation of the circulation of water or cleaning solution from the inlet 90 in order to distribute the cleaning solution throughout the manifold 20 and, of this

5

so, throughout the bag 10, as is desirable to obtain an effective cleaning of the entire bag 10. The spot welds 86 also define openings therebetween through which the cleaning solution will be distributed to clean the entire bag 10. It will be understood that the dimensions of the point welds 86 can be modified to obtain the desired flow characteristics, allowing additional or greater flow characteristics 86 to be obtained with smaller or larger flow characteristics and the welds 86 having a larger diameter to reduce flow characteristics. In addition, it is possible to modify the separation between the point welds 86 to obtain the desired flow characteristics through the spaces between the welds 86.

Additionally, as shown in the embodiments of Figs. 10 and 11, the spot welds 86 that form the bottom of the manifold 20 may be staggered with respect to the adjacent welds 86 to facilitate the formation of turbulence in the cleaning solution when leaving the collector 20 for effective dispersion throughout the bag 20. It is also possible to modify the staggered arrangement of the welds 86 to create the desired turbulence and flow characteristics from the manifold 20. The turbulence created by the lower staggered welds 86 also facilitates the distribution of the cleaning fluid to the stoma and the stoma opening of the bag 10 for effective cleaning of the stoma and the area surrounding the stoma opening. In order to facilitate the desired distribution of the cleaning fluid in the bag 10, it is possible to form spot or linear welds 86 to create a larger area of restriction to the flow rate of the cleaning fluid, as shown in these embodiments, said shapes being able to be formed. areas adjacent to the inlet 90 in 94 to cause dispersion of the cleaning solution flow away with respect to the central part of the bag 10. In addition, said enlarged restriction areas may be formed in the lower outer portions of the manifold 20 to limit the flow in these positions to some extent in order to facilitate the dispersion of cleaning solution throughout the manifold 20. Furthermore, it is possible to form spot welds 86 at the top of the manifold 20 to facilitate creating turbulence in the cleaning fluid when it enters the collector 20 and leaves it. In the embodiments of Figs. 10 and 11, the number of upper spot welds 86 of the manifold 20 is different to obtain alternative effects in the creation of turbulence. As will be understood, when the cleaning solution enters the inlet 90 and in the collector 20, the solution will be effectively dispersed throughout the collector 20 and will be released turbulently from the collector to be dispersed throughout the bag 10 of turbulent way to clean the bag 10 completely, and the turbulent solution will disperse through the stoma and the area surrounding the stoma opening to clean them effectively. As can also be seen in the realization of Flg. 11, the presence of larger openings between the welds 86 adjacent to the outer ends of the manifold 20 is possible to facilitate the distribution of the cleaning solution in said positions. Various modifications in the configuration of the manifold are contemplated, such as a configuration of the welds different from that of the point welds, in the dimensions or in the relative configuration of the welds or the like. The welds 86 of the manifold 20 may be arranged in a modulated manner to orient the flow of water throughout the colostomy bag 10 and to create turbulence in order to improve the cleanliness of the bag. The modular arrangement of the openings 86 directs the water downwards, through the entire colostomy bag 10, through the side walls of the bag and through the stoma opening, while at the same time obtaining an economical way of manufacturing and shaping the manifold 20 and its elements.

As shown in Fig. 12, it is possible to arrange a small reservoir 100 formed in the supply line 42 and having a valve or actuator button 102 that can be used selectively to dispense a small amount of cleaning materials, deodorants , disinfectants, acid neutralization and / or lubricants in supply line 42 for introduction into the bag 10. The introduction of said materials makes it easier to clean and / or eliminate odors from the bag and / or use, facilitating cleaning, disinfection and / or humidification or other stoma treatment when the bag is attached during use to the patient. The system to achieve this can also be a separate system if desired, which could be selectively linked to the input line 42. Various modifications are also contemplated to achieve similar functions.

It will be understood that the scope of the invention is not limited to the descriptions and explanations shown above, but that the invention comprises any embodiment and all embodiments within the scope defined by the following claims.
